When are egress stairs not necessary in Single Family Residences?

    I have a home in the city of Los Angeles that requires a winding/circular staircase in the entry way. It already has another secondary stairs going to the back exit. Will it require the winding/circular staircase to meet egress code since there already is another stair case? In other words does need minimum tread width etc.per code.

    Also, we want to install a prefab spiral stair case to the roof deck garden area . Since the roof deck is not a sleeping area, and not considered habitable space, can it just get a non-code compliant spiral stair?

    STAIRWAY, SPIRAL. A stairway with a plan view of closed circular form and uniform section-shaped treads radi- ating from a minimum-diameter circle.

    R311.7.10.1 Spiral stairways. Spiral stairways are permitted, provided that the clear width at and below the handrail is not less than 26 inches and the walkline radius is not greater than 24 1/2 inches. Each tread shall have a depth of not less than 6 3/4 inches at the walkline. All treads shall be identical, and the rise shall be not more than 9 1/2 inches. Headroom shall be not less than 6 feet 6 inches.

    Spiral stairs are already a bit dangerous even if they meet code. The plan to install spiral stairs that are less than code seems fraught with peril.

    I have installed a code compliant spiral staircase kit in my home. My guests always seem to have problems going down these steps. The stairway came with horizontal bars across the riser opening to be code compliant, I think my guests are bringing their feet down to close to the risers and their heel gets caught on the bar. Thank goodness these bars can slide out of brackets on the treads above when stepped on otherwise people may be falling down the steps. My house has a permit for a second floor that is 90% finished. I think it would be safer to take these bars out and then put them back in for a final inspection and then take them out again.
    Has anyone else have this problem?
